They seem to run the same either way. I just thought my spark plug may last a little longer if it was on top. I have the Homelite 30 with the 28 carb and it was a lot of power for this plane. It is not under powered even with the extra weight and the 21st Century fabric on it. The engine will turn a Dyna Thrust 18-8 at 7600 and idle at 1800.

Leave the landing gear with the 1/4" rod. You will need it. But use light weight wheels.

I've got to go but will be back later today.

Enjoy,

Jim
